The picture shows a small section of Sea Island Georgia.http://seamless.usgs.gov/website/seamless/viewer.phpThe resolution is 3 inches to a pixel!! The download size for this picture is 890mb !!So, if you want really hi res for FSX here it is.Regards,Dick BoleyA PC, an LCD, speakers, CH yokeSection from USGS:http://forums.avsim.net/user_files/171522.jpgFrom FSX a small 2.19mb BGL, 7cm detail set in FSX:http://forums.avsim.net/user_files/171523.jpgAnd from FSX at a detail setting of 1meter/pixel:http://forums.avsim.net/user_files/171524.jpgAnd at 60cm/pixel:http://forums.avsim.net/user_files/171525.jpg

Hi Dick.Good find! I wonder how the Sea Island folks like us peeking into their yards like this. :-lol I'll play with it, and see what we can find. Looks like FSx and resample have no problem with it. 3" is 7.62cm, so the sim should resample and show it just fine.Dick

The second picture in the previous message is at a 7cm setting in FSX. Problems do develop with some of the cars and white areas looking at it in TMFVIEWER and in FSX. There is a 6 inch/pixel available as well. Downloads and file sizes more reasonable. I believe that during the FSX island demos there was a Microsoft comment that some improvement in the resampler may be possible. However, once in to FSX there is no great difference between 3" and 7" pictures at a sensible altitude. The concern becomes more with color and consistency. I am trying a larger area at 7". See below. Note washed out grey/cement areas. Seems to be caused by very white, highly reflective, areas.Regards,Dick BoleyA PC, an LCD, speakers, CH yokeTMFVIEWERhttp://forums.avsim.net/user_files/171528.jpgGlobal Mapperhttp://forums.avsim.net/user_files/171529.jpgPicture from FSX at 500ft altitude.

I've been looking at 30cm/12" photoscenery, and have built up a test area of several square miles now. One problem I'm seeing is blurries in FSX that I don't see at lower res (say 1.2m/pixel). If I pause the sim, the texture loader does catch up and sharpen the images. Is there anything I can do to improve this situation? The only tweak that seemed to make a difference was TEXTURE_BANDWIDTH_MULTI, but things still fall behind.Some questions on generating hi res scenery:1) Is there a sweet spot for BGL file size? I've generated each around 70-90MB so far?2) Likewise for compression in resample.exe? Used 85% so far.3) Is it beneficial to downsample your scenery to a lower res, say from 30cm to 1.2m/pixel and to have both low and hi res available for the same area? My idea is that FSX uses the low res for distant areas, and the hi res surrounding your plane. Saves FSX having to downsample the hires while in flight. If this is the case, what resolution should the "low res" be at?Simon

The blurred textures are an issue with slower PCs as they try to catchup. The FIBER_FRAME_TIME_FRACTION=0.4 in FSX.cfg/Main is normally 0.33. Try messing with that. My TEXTURE_BANDWIDTH_MULT=400 .I do not know of any sweet-spot for photo BGLs size. I have 2.98gb of photo textures for California. Many of the BGLs are 200mb or larger. I see no big issues with blurred textured (delayed rendering. PC is 2ghz single core and 1 gb of memory. 3 years old..... Al of the usual try all slider to the right except for scenery detail. I run this at 60cm for 1 meter hi-res.The approach I use is 1 meter hi-res around the airports with extensions covering the flight path. The I use 4.7 meter for all else. Exceptions are points of interest which get 1 meter.With 1 meter textures from Terraserver/JD Cox I do not need a synthetic airport and instead just use the photo for runways and taxiways.As I illustrate you can get much finer detail (yes it does work) but a two runway airport requires over 1gb of downloaded data at 6 inches per pixel. Not worth it. The problem is that some areas that have very high res do not have any lower res stuff so you can't use it unless you just want a small area.Regards,Dick BoleyA PC, an LCD, speakers, CH yoke
